while fucking a woman doggy-style: when you are about to cum, you pull out and sandwich your penis between her buttcheeks, thus creating the image of a hot dog in a bun and expel your seed all over her lower back.

friend1: yo man i gave that girl a ballpark hot dog at the party last night! it was sick!
friend2: No wayyyyy dude! im so proud of you! *high five*
